Qwt from Windows to Linux Porting

@shivaVMC said in Qwt from Windows to Linux Porting:

I dont have QtSvg in qtbase/lib/libQt5Svg.so*

ok then you have to compile it. If you still have your Qt build directory, go into qtbuilddir/qtsvg and run make && make install there.

@sierdzio
Hi,
I have cloned qtsvg module I followed below steps
~/raspi/qt5/bin/qmake -r
make
make install
Then I compiled the qwt-6.1.3 using
~/raspi/qt5/bin/qmake -o Makefile qwt.pro
make
make install
it went fine(no error's relating to svg Module) till last stage, but I came up with new error as below

Project ERROR: Unknown module(s) in QT: designer
Makefile:174: recipe for target 'sub-designer-make_first-ordered' failed
make: *** [sub-designer-make_first-ordered] Error 3

I have cloned qttools module and
~/raspi/qt5/bin/qmake -r
make
During make I faced new errors again as below,
/home/user/raspi/sysroot/usr/lib/arm-linux-gnueabihf/libproxy.so.1: undefined reference to `VTT for std::__cxx11::basic_ostringstream<char, std::char_traits<char>, std::allocator<char> >@GLIBCXX_3.4.21'

Makefile:42: recipe for target 'sub-contextsensitivehelp-make_first-ordered' failed
make[2]: *** [sub-contextsensitivehelp-make_first-ordered] Error 2

So can I know which module I need to clone to avoid this error?
or any other suggestive fix for this type of error

All these modules should be build together with your Qt build. When you did your Qt cross-compilation, did you do that on whole Qt source code or only qtbase or something?

shivaVMC

@sierdzio
I cloned qtbase and followed

./configure -release -xkb -svg -fontconfig -openssl -opengl es2 -c++std 11 -device linux-rpi3-g++ -device-option CROSS_COMPILE=~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf- -sysroot ~/pi_raspi/sysroot -opensource -confirm-license -prefix /usr/local/qt5pi -extprefix ~/pi_raspi/qt5pi -hostprefix ~/pi_raspi/qt5 -no-use-gold-linker -v
make -j4
make install

So I did only on qtbase.

Can I know the steps to build all modules together with Qt build?

shivaVMC

@sierdzio
I followed this https://wiki.qt.io/RaspberryPi2EGLFS#Step_by_step site

Any changes in steps-by-step part of above site,please help me on it

@shivaVMC for a full Qt build you should read https://wiki.qt.io/Building_Qt_5_from_Git

its main difference should be the cloning part, configuration should be similar to qtbase alone.

sierdzio

Use whole Qt source code, not only qtbase. Qtbase contains only some basic modules like QtNetwork, QtCore etc. No widgets, no qml, etc.

Here's a short script to get you going with full Qt:

export QTVER=5.11.1
wget http://download.qt.io/official_releases/qt/5.11/$QTVER/single/qt-everywhere-src-$QTVER.tar.xz
tar -xaf qt-everywhere-src-$QTVER.tar.xz
mv qt-everywhere-src-$QTVER $QTVER-src
mkdir qtbuild
cd qtbuild
../$QTVER-src/configure -device linux-rasp-pi3-g++ -opengl es2 -confirm-license -opensource -release -nomake examples -skip qtwebview -skip qt3d -skip qtquick1 -skip qtwayland -skip qtvirtualkeyboard -skip qtwebchannel -skip qtwebengine -skip qtscript -skip qtscxml -skip qtspeech -skip qtpurchasing -skip qtgamepad -skip qtserialbus -skip qtlocation -no-use-gold-linker -device-option CROSS_COMPILE=/path/toi/your/toolchain- -sysroot /path/to/your/sysroot -prefix /home/pi/$QTVER-cross -extprefix $PWD//../$QTVER-cross -hostprefix $PWD/../$QTVER-build -v

okay...Thank You Thanks alot.
I m following the link https://wiki.qt.io/Building_Qt_5_from_Git and your mentioned short script..I will get back,if any issue I m facing.

Does not matter how you get Qt sources (from git like in your link or from archive like in my script), the result will be the same. Just remember to add all those -skip flags to configure line (and keep your sysroot and toolchain from the EGLFS guide).

I have tried to compile Qt build for Qt_V5.7.1,but I m facing the below error

.obj/qeglfskmsintegration.o:(.data.rel.ro+0x74): undefined reference to `QEGLDeviceIntegration::destroyNativeWindow(void*)'

Can I know which plugins/lib are missing or which lib I need to install?

Note: Also available for Linux: linux-clang linux-icc

Note: Dropped compiler flags '-pthread' when detecting library 'glib'.

Note: Dropped compiler flags '-pthread' when detecting library 'gstreamer'.

Note: Dropped compiler flags '-pthread' when detecting library 'gstreamer_app'.

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/home/user/raspi_QtBuild/qt5pi'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

When I perform --- make -j4

Why do you say you're compiling Qt 5.7.1 when the output you paste indicates 5.11.1?

Anyway, I've never seen that error, I don't know how to fix it.

shivaVMC

@sierdzio
Qt_v5.7.1 .tar.xz file was already with me ,till Qt_v5.11.1 gets dowloaded I have compiled Qt5.7.1..... For both the version different errors I m facing as mentioned above

sierdzio

@shivaVMC said in Qwt from Windows to Linux Porting:

PFNEGLCREATEPLATFORMWINDOWSURFACEEXTPROC

This comes from EGL headers. You probably don't have all Qt dependencies installed in your sysroot.

Install necessary dependencies. Try with sudo apt build-dep qt5-qmake qt5-default on your Raspberry Pi. You may also try sudo apt install "^libxcb.*" libx11-xcb-dev libglu1-mesa-dev libxrender-dev libatspi2.0-dev libdbus-1-dev.
Update your sysroot and fix symlinks.
Recompile Qt. Make sure to check configure output that it says EGL support is on.

shivaVMC

@sierdzio
Hi ,
Finally it got compiled...I m success on compiling and installing Qt-V5.11.1
Now,please suggest me that which qmake shall I take to compile qwt-6.1.3

I m finding two qmake

/home/user/raspi_QtBuild/Qtver-5.11.1/qtbase/bin/qmake
/home/user/raspi_QtBuild/qt5/bin/

Thanks In advance for your help& support.

sierdzio

@shivaVMC said in Qwt from Windows to Linux Porting:

-hostprefix ~/raspi_QtBuild/qt5

This is your host prefix, so you should use the qmake from /home/user/raspi_QtBuild/qt5/bin/.

You can verify which Qt version that qmake comes from by running:

/home/user/raspi_QtBuild/qt5/bin/qmake -version

shivaVMC

@sierdzio
Everything went fine,but when I m performing
/home/user/raspi_QtBuild/qt5/bin/qmake -o Makefile Myproject.pro
.qmake.stash is created

then when I perform
make -j4
I get below error's ,please suggest on this

/home/user/raspi_QtBuild/sysroot/usr/lib/arm-linux-gnueabihf/libQt5OpenGL.so.5: undefined reference to `operator delete(void*, unsigned int)@CXXABI_1.3.9'

collect2: error: ld returned 1 exit status

I m head cracking on this,even I did on raspberrypi3 board

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install mesa-utils

sudo raspi-config
Select 7 Advance Options
A6 GL Drivers
selected GL (Full KMS) Desktop Drivers
Ok-> Finish->Reboot.
My Screen went black with cursor blinking.

Any other commands,that I can do to get support for this libQt5OpenGL...This is the only step I stuck to complete the things of my project

sierdzio

Hm, I've never seen this error message, so I can only guess.

Can you show build output (for Qwt) - I'd like to see at least one line calling the compiler and one line calling the linker. Need to know if all the compilation flags are correct.

Oh, they are not printing the build commands in Qwt :-( Don't they have some verbose mode or something?

If yes, please use it and paste the output here. If no, then please paste the beginning of Makefile that is produced - the section where all compilers and flags are set up.
